Top Speed's Cat Back System Installation

You need to "fiddle" with the whole assembly. Keep your connections loose until everything is in place. Definitely NO cutting required.

Okay thanks, I tightened the flanges behind the primary cats, probably my first mistake. Tomorrow i loosen every joint up and then have at it once again. thanks for the tip, I'll let you know how it goes.

[BruceH]

Yes, that will help, good luck!

Son of a $%&*!, that system just won't fit together neatly, having to resort to buying adapter pipes to get it better. Left side works out fine, right side no chance. Looosen, tighten, curse, pray, nothing is working, C4 is next. Just won't work, the muffler Manza muffler isn't precisely made, so I see some problems in how it is not lining up well with the test pipes, but a few more hours and it should be good.

Anyone have a suggestion on putting this thing together? I think I am going to take it all apart and work backwards, from Muffler to primary cats. This thing just shouldn't be that diffcult, should it? I am no expert mechanic but I'm also no newb with turning a wrench, so I am getting a little perplexed on what in the H E double hockey sticks is going on. I am open to suggestions, PLEASE!

[BruceH]

I am not a master mechanic either and I got a little frustrated too when installing mine. My best advice is take your time and keep everything loose, including the muffler. You have the cat delete pipes and the TS muffler, correct? If so, it will all fit. One question, on your cat bypass pipes, you don't have two identical ones do you? I seem to remember a while back, someone got shipped two of the same pipes, not a left and right. Double check that.

Yes I have those items and no the test pipes are a left and a right one. I'm going to take another whack at it tomorrow. Thanks Bruce I will continue to fight on. I know it must go together, just going to have to give it another shot.

Victory Bruce, but it did not fit as ordered. Ended up cutting 2 1/2" from left side test pipe and 3 3/8" from right side test pipe. Fit perfect now. Sound is really great, even at low rpm it sounds fantastic. I have heard that many say the sound only improves, well I can't imagine it sounding any better than it does now, but I'll welcome any additional improvements. Actually the sound is great at all rpm ranges and it has a nice burble sound when backing off the go-go pedal. I couldn't be happier and knowing I don't have to be upside down under the car for a while makes my neck happier too.

Woo Hoo! Glad you got it in! Puzzled as to why it didn't fit, but the end result is all that matters. It will blow fiberglass insulation for a while. You will see it on the rear bumper. Don't brush it off! Doing so will scratch your paint. Just use water to wash it off. Enjoy

Thanks Bruce, so glad it is done and yes white shiite is all over the back bumper. Will not brush off, wash it off only, warned my wife "not to help and wipe off".

Wow I am impressed, sounds awesome. However my gas mileage has totally tanked, might because I now floor it everywhere I go, just love that sound.

Yea, I never get very good gas milage Sounds even better going through underpasses

Again, I am wowed with the total change of sound coming out of my 01. Test pipes and new muffler have totally sexxed up that cars sound. It now has people turning their heads as I pass them on the sidewalk (at 90, lol). Actually seems to have turned this base unit into a beast, at least it sounds that way.

Guys,

I could use some advice from those of you with the test pipes and TS exhaust. I installed the exhaust but felt there was too much drone, however I still had all 4 cats in my '01 S. I put the stock exhaust back on, but have since installed the 2nd cat delete (which is great).

I live in the mountains, which can really make drone in an exhaust stand out as hills in higher gears can put the car in the 'drone sweet spot'.

Question - does running the TS exhaust with the test pipes in place reduce drone? This is compared to TS exhaust with all 4 cats in place.

Thanks!

Gary

Take a look at my previous posts on this. I do not have any drone to speak of. I have the pipes and the exhaust. I also used better clamps than what came with the pipes.

A few weeks ago I installed headers/high flow cats with the rear cat delete pipes and a Dansk sport muffler. Love the setup but I had a slight leak at the cat delete slip joint. Because of this post I went to Napa and ordered two of the 2 " clamps. I installed them today wow they do make a difference ! Zero leaks and it seemed to very slightly alter the sound of the exhaust for the better. For 22.00 with tax it was a great investment. Appreciate the tip

IMO, those clamps make a big difference. Glad they worked for you

Look at page one of this post, scroll down about three quarters down there is a pic of the clamp on the blister card with the part number.
