Default New Exhaust System ----> Need your feedback!!

Hi Everyone,

We are in the process of developing a brand new exhaust system for the 98-02 LS1 fbodies. The system is going to be 3" T409 stainless steel from the intermediate pipe all the way to the tailpipes (as opposed to other aftermarket catbacks which use 2.5" tailpipes. Instead of the usual more restrictive transverse muffler used in other systems, we are planning to use one stainless steel resonator in each tailpipe (2 in total).

The system will be a straight through design and the flow will be extraordinary. It will also be quieter than the loudmouth but louder than a conventional catback which is a request we have gotten from many customers.

There would be no tips included in the system (to keep costs down) but it would have 3" slash cut tailpipes.

Question: Is this something you would be interested in? Would you prefer it to be louder with two resonators or quieter with two bullet mufflers instead?

We are shooting for an introductory price point of 499.99. Is this a price you would be willing to pay for a high flowing, stainless steel, complete 3 inch system?

Your feedback is greatly appreciated. We like to involve members in product development!

Thanks!

Hmm, would a cut-out be loud enough?

not another catback

companies should be designing bolt-on true dual systems...the whole thing...headers, xpipe, mufflers, tips...

I think that most of the people that have enough power to make this catback worthwhile, either run true duals or a cutout anyways. I don't see much product base for this imo.

The dynomouth, borlamouth etc. has seemed to become the solution to the "my loudmouth is too loud and raspy" and would still be cheaper than this.

Two bullets in the tailpipes won't elminate rasp with LTs/ORY. I know this because a friend of mine has Grots with an ORY and two twelve inch bullets welded into his tailpipes and it still sounds like crap.

Default Feedback...

Thanks for the feedback everyone.

Ton answer some questions:

A true dual kit exitting out the back or side is not an option as there just isn't room on the fbodies to do it without having rattling, banging or sacrificing ground clearance. The cost would also be very high since you would have to two pipes running the full distance.

There is no way to get the cost down if we build the system in full stainless with two resonators or two bullet mufflers. We could do a system similiar to the loudmouth (1 resonator) but with 3" tailpipes for a 399.99 pricepoint.

We could do a conventional T409 except for the muffler system with a transverse muffler and twin tailpipes for around 369.99 but I think there are plenty of systems with a similiar configuration around on the market right now.

Keep the feedback coming!!

Thanks!

Personally, I'd like to see a quiter exhaust setup, maybe I'm just getting old. I am so sick of abnoxiously loud, raspy, crappy sounding systems. Come up with something with a more mellow tone but still sound good and I'm all over it , whatever the cost. My .02

For the average person putting an exhaust system on their car, I would emagine that exhaust tips would be a pretty important thing to have. Most people don't have the inclination to have tips welded on when they can buy a system with them already on. Just my 2 cents.

Although easier said than done, I think what would really sell is a 3 inch true dual system that had nice tips.

Dan,

There are already some systems like that. You would probably like the Corsa, Magnaflow or Even the Random Technology system. The Corsa would would probably be the most mellow of those.

If you want a deeper sound, you could go with a Mufflex 3.5 or 4.0" system. I have the 4.0" system on my personal vehicle and it sounds fantastic... very mellow and smooth.

I think if you guys could make something that works very well with long tubes and an ory, you could get some people interested. There don't seem to be many catbacks that are loud, but sound good with LT and an ORY. For full 3 inch, and SS, I think maybe 450 could get more people interested.

Also another idea, maybe you could make a system similar to the loudmouth, but offer better muffler selections than SLP.

kinda what i was thinking...stick a "custom" muffler of the consumers choice in it...or just use a basic number of mufflers, say 3-4 different ones and let the consumer decide what he/she likes best...

ex: bullet, chamberd muffler, xr1, magnaflow bullet just for example..

2nd idea: maybe make the system kinda based off the borla design with just one muffler, and a cutout style tail pipe with a adjustable plate feature...just let the consumer pick the muffler they would like to put in place of the muffler...then again, that might be kinda hard to make with a 450-500 goal in price...anyway, just throwing out idea's..

Thanks for your feedback. SLP already has a modular system with a choice of a single resonator or single muffler. That is why we proposed two mufflers in the tailipes. This would provide better ground clearance, superior sound control and superior flow. The system woudl also be complete 3". Of course, two mufflers cost more than one so it raises the price.

Exhaust tips add substantially to the cost of any system. That is why Corsa, Borla etc that come with nice tips are so pricey. It is very difficult to find 3" ID tips so the 3" tailpipes dictate no tips included with the system to keep prices down. If we did 2.5" tailpipes, we could use our dual stainless tips which look great but would add about 80.00 to the price.

Given all the permutations of long tubes and offroad pipe, there is no easy to way to make a cat back to work with them all. That is probably with TSP has their system exit under the car as it makes it cheaper and easier to make.

ya i see what you are saying...my personal option is something in the loudness range of a GMMG but somehow eliminate the rasp...i know that is harder to do then say...im interested to see what you come up with though...

If you're looking to keep the price down, drop the 3" tailpipes. It gains the customer nothing and drives the price of the system higher. The flow area of the single 3" pipe that would feed the catback is 7.1 square inches. Dual 3" tailpipes would double that area and reduce EG velocity noticeably. Dual 2.5" tailpipes are still larger than the single 3" feed at 9.8 in². I don't know if the dual 3" tailpipes are just a marketing decision or what, but from a cost cutting perspective, I think you have a lot to gain and nothing to lose by going with a smaller pipe. JMHO.

The 3" tailpipes do not cost much more but they do impact the sound quality making the tone deeper. We could do 2.5" tailpipes and mufflers instead which would drop the price maybe 20-25.00 if that is the consumer preference.
